ROBERT H. EDMISTON, OF AMER-IOUS, KANSAS.

GRAIN-METER.

SPECIFICATION forming part of Letters Patent No. 261,516, dated July 18,1882, 7 Application filed November 22, 1881. (No model.)

I all whom it may concern: 7

Be it known that I, ROBERT H. EDMISTON, of Americus, in the county ofLyon and State of Kansas, haveinvented a newand useful Improvement inGrain-Meters, of which the following is a full, clear, and exactspecification.

The present invention is an improvement on the grain-meter shown inLetters Patent granted to me April 22, 1879, and has for its object torenderthe operation more perfect and reliable.-

The invention consists in certain novel features of construction andcombination of parts,

hereinafter described and claimed.

In the accompanying drawings, Figure l is a plan view of the apparatuswith the cover partially removed. Fig. 2 is a vertical section on line00 m of Fig. 1. Fig. 3 is a side elevation of the meter. Fig. 4 is ahorizontal section on line y y of Fig. 2. Fig. 5 is a vertical sectionon line 2 z of Fig. 2, and Fig. 6 is a horizontal section on line to wof Fig. 5.

Similar letters of reference indicate corresponding parts.

A is a bin, preferably of rectangular form, and divided in its lowerportion by a cross-partition, 1), into two compartments, a m of equalsize. The bottoms of the compartments are inclined or hopper-shaped, andare provided with deliveryopenin gs c 0, over which 'are gates d, hingedto open outward.

c c arespouts from the openings 0.

The partition I) is slotted to sustain an inner box or hopper, e, thatis adjustable up and down on the partition. A partition, f, divides thebox e into compartments 0 0 which communicate with the respectivecompartments a a h is a partition at right angles to partition f,forming passages from the spaces a a to the upper part of box 0.

i i are openings in the upper part of partition h, fitted with spouts i.

k is a rocking frame hung in box a on a crossaxis, Z, so as tooscillate.

k k are pans hung by pivots at the opposite sides of frame 70 andbeneath the spouts t". These pans are open at the top and one end,

and beneath them are fixed projections a,

which cause each pan to tilt when it is moved down by the oscillation offrame 70. The axis l of frame 70 extends through the side of hopper aand through a slot, m, in the side of bin A, and carries a double-crankarm, a, one end of which has a pin, 72/, entering the slot 0 of one armof the three-armed lever 12. This lever p is hung by a fulcrum, q, onthe side of bin A, and its other'two arms connect by links 1" r withcam-dogs r 1", which are hung by suitable pivots in the delivery-spoutsc.

s is the feedspout, hung by an axis, a, in a slot of partition f inhopper a, so that the spout can oscillate from side to side and deliverthe grain in to either of the compartments 2 around the upper end oflever a.

v v are spouts or chutes fixed beneath spout s, and inclined in oppositedirections, so as to carry the grain from the spout s to the spaces 0 eh h are spouts fixed on partition I) at opposite sides, and extendingthrough the partition. These are placed to receive the grain from thepans k. The bin A and hopper e are t is a yoke fixed on spout sandextending provided with removable covers 9 for exclud- 7 ing dust.

In the operation of the machine, spout 8 being in position to feed thegrain to one compartment, e or 6 of hopper c, the grain passes to onecompartment, a or a of the bin. gate cl of that compartment is kepttightly closed by the dog r, which is pressed against the gate inconsequence of the inclined position of lever 12. As soon as the binfills up to The the bottom of hopper c the grain will rise in 8 thepassage at the side of partition it until it reaches the opening 2',when it will run to the pan 7c at that side which is elevated untilthere is sufficient weight to bear the pan down. This rocks the frame70, the spouts isswung to the opposite side, and the lever p shifted.The grain then passes to the other compartment, the gate of which isclamped by the movement of the lever, while the gate of the first-filledcompartment being released the grain runs out. By raising and loweringthe hopper e the quantity at each discharge can be accurately regulated.

As shown in Fig. 3, there is a gage on the side of the hopper c, whichis for use in regulating the hopper. v

Screws or other devices may be combined with the hopper for raising andlowering it.

The spouts h carry the grain discharged claim as new and desire tosecure by Letters Patent 1. In a grain-meter, the combination, with thebin A, provided with the compartments a (o of theadjustablc hopper 0,provided with the compartments 0 c, the partition h, having openings 1',and the oscillating frame k, carrying the pans k, substantially asherein shown and described, whereby the quantity at each discharge canbe accurately regulated by raising or lowering the said hopper, as setforth.

2. The combination of spout s, hopper 0, provided with chutes o andapertured partition h, oscillating frame 70, pans k, and divided bin A,substantially as shown and described.

3. In grain-meters, the spouts h, combined with divided bin A, rockingframe it, pans 7c, and hopper e, substantially as and for the purposeset forth.

4. In grain-meters, the combination, with the bin A, provided with thespouts 0, having hinged gates d, the oscillating frame 7c, and thefeed-spout 8, provided with the yoke t, of the double-crank arm n, thethree-armed lever 12, the link 1", and dogs 1", substantially as and forthe purpose set forth.
